WiFi is almost everywhere. Wherever you go there are WiFi packets emitted by smartphones, tablets, computers, access-points, etc. All WiFi packets “flying” around are divided into four main groups (802.11 Frame Types) – management, data, control and extension. In this article we will take care of capturing some interesting subtype packets of management group (Beacon … Read more
In this article I will show you how to make a WiFi beacon spammer on ESP8266. Beacon spamming involves broadcasting a valid IEEE 802.11 beacon frames using fake SSIDs and MAC addresses. This educational project is hackable and easy to get running. The code is on GitHub, here. What is WiFi Beacon? WiFI beacon frames are used by … Read more
This is my another example of simple and inexpensive WiFi packet analyzer (also known as a WiFi sniffer). The heart of this project is ESP8266 WiFi module which is able to work in a promiscusous mode. This module allows IEEE802.11 network packets capturing for further analyzing. Because of the fact that ESP modules don’t listening on all channels at a time, additional code … Read more
This experimental project shows how to build a simple and inexpensive WiFi packet analyzer (also known as a WiFi sniffer). The heart of this project is WiFi module of ESP32 which is able to work in a promiscusous mode. It means that this clever chip allows IEEE802.11 network packets capturing for further analyzing. Because WiFi … Read more
The ESP32 is a low cost, low power microcontroller with integrated 2.4 GHz Wi-Fi (up to 150Mbps) and dual-mode Bluetooth (classic and BLE), which employs a dual-core Tensilica Xtensa LX6 microprocessor. ESP32 is created and developed by Espressif Systems, a Shanghai-based Chinese company, and is manufactured by TSMC using their 40 nm process. It is … Read more
